It is named after mathematician Ronald Graham, who used the number in conversations with popular science writer Martin Gardner as a simplified explanation of the upper bounds of the problem he was working on. In 1977, Gardner described the number in Scientific American, introducing it to the general public. The number is defined using Knuth's up-arrow notation: G = f^64(4) where f(n) = 3 ↑^n 3. It is so large that the observable universe is far too small to contain an ordinary digital representation of Graham's number, assuming that each digit occupies at least one Planck volume. However, its last digits are known: ...386272486927329881373587889168515006160501673584116227672333074669421008006735953730310243735517753922322677421313366870503298635688960788950100801120015233580461812803716487808643838703234072322610425841641387007421700085811363376116802875136000000000000000000000000000000000000000000
